Layer contours

The layer contours are the boundaries of the layers in the view. These contours are used for input and automatic delimitation of slab layer plates, slabs and for quantity surveying.

The automatic determination of the layer contours takes into account the extent up to the contour edge, the openings and the penetrations of wall edges with core layers and shells on the top and bottom of the slab panel.

If contours have been post-edited by the user, they will not be automatically adjusted when changes occur in those areas, because the manual modifications would be lost each time. It is often easier to rework the affected slab panels manually. If an automatic recalculation is desired after a change, the 'Prime shape' function is used.

Slab edits - New contour

For each layer, additional new contours can be entered. It must be specified whether it is an outer or inner (opening) contour. Several layers can be defined at once with a new contour. Contour lines must not overlap. Outer contours must not lie within another contour; inner contours must lie within an outer contour.

Slab edits - Contour - Move line

In this dialog box, the contours of each individual layer of the slab panel can be enlarged or reduced by any value. Negative numeric values reduce the layer contour. The displacement of the contour lines is performed as a parallel offset to the original line. Contour areas adjacent to a modified line are automatically adapted to the new contour situation.

By entering a value greater than 0.00 under 'Offset' and using the 'Whole contour' function, all lines of the selected layers will be shifted by the desired value.

In the 'Contour cut' function, each individual layer edge can be shifted by any value. Multiple layers can also be selected for editing at the same time; these are then processed consecutively in the order of their position in viewing direction (from top to bottom). For clarity, the currently edited contour line is indicated with an arrow, which also shows the positive/negative direction. If multiple layers are selected, the 'End' command first finishes editing the current layer contour and jumps to the next selected layer.

Using the 'Pick' function, the contour line to be moved can be selected with the crosshair. If the offset value is set to 0.00, any contour line can be chosen with the crosshair and moved graphically or with the help of the temporary functions.

With this function, the individual layer contours can be modified specifically. The reference polygon of the slab panel remains preserved.

Slab edits - Contour - Replace line

After selecting the layer contour, a single contour line can be chosen. It is dissolved and a rubber-band from the start to the end point is displayed at the mouse cursor. Now any additional lines with all input options can be entered in place of this line. If the process is ended with the right mouse button, the contour is automatically closed.

Slab edits - Contour - Delete point

After selecting the layer contour, a point of the contour can be deleted. The two affected lines are replaced by a line from the start point of the first to the end point of the second line.

Slab edits - Contour - Prime shape

The automatic determination of the layer contours takes into account the extent up to the contour edge of the reference polygon, the openings and the penetrations of wall edges with core layers and shells on the top and bottom of the slab panel. If the reference polygon has been post-edited by the user, previously changed layer contours are not automatically adjusted, because the manual modifications would be lost each time.

The 'Prime shape' function performs an automatic recalculation of individual or all layer contours of the current slab panel. The recalculation adapts the layers with their contours again to the reference polygon.
